Clickable URIs/links in terminals is a standardized thing: https://github.com/Alhadis/OSC8-Adoption

Detect that support (e.g. using ANSI cursor position request) and set a console flag for the session. Then allow custom strings when supported or use @-codes to do the special expansion when displaying URLs.

Actually, reading the spec again, there is no way to detect if it's implemented. :(

But on the plus side, it should also be transparent when the client doesn't support it (assuming the client isn't broken)

So in the example, `printf '\033]8;;http://example.com\033\\This is a link\033]8;;\033\\\n'`, a non-broken but non-supporting terminal would just eat the URL and only display "This is a link"?

Right, there's two OSCs there... "\\033\]8;;http://example.com\\033\\\\" and "\\033\]8;;\\033\\\\". Those would be stripped.

Right, there's two OSCs there... "\\033\]8;;[http://example.com\033\\](http://example.com%5C%5C033%5C%5C%5C%5C)"
and "\\033\]8;;\\033\\\\". Those would be stripped.

Well, that's kind of lame. :-( I was hoping the URL would at least be *displayed* for terminals that don't support OSC 8. And that would've made autodetection easy too.
